Area of square is S×S

side X×X=9

X equals 3

4×3=12

12×12=144

The area of a square of side 4x will be 36 square units.

A square is a four-sided polygon, whose all sides are equal in length and whose opposite sides are parallel to each other.

Also, each vertex of the square has an angle equal to 90 degrees.

The area of the figure is the product of the length of the side.

Area of square = Side × Side

The area of a square with side x is 9. Then the area will be

Area = 4x

Area = 9 × 4

Area = 36

The area of a square of side 4x will be 36 square units.

Answer:

[tex]\frac{48}{7}[/tex]

Step-by-step explanation:

The common ratio r is

r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{\frac{4}{7} }{-\frac{1}{7} }[/tex] = - 4

To obtain the next term multiply the previous term by - 4 , that is

next term = - [tex]\frac{16}{7}[/tex] × - 4 = [tex]\frac{48}{7}[/tex]

Add the 3 ratios together: 1 + 3 + 2 = 6

Divide perimeter by total:

30/6 = 5

Multiply each ratio by 5:

1 x 5 = 5

3 x 5 = 15

2 x 5 = 10

Answer:

m<DEF = 47°

Step-by-step explanation:

Given:

m(DEF) = 266°

Required:

m<DEF

Solution:

m<DCF = ½(m(DEF)) (Inscribed angle theorem)

Substitute

m<DCF = ½(266°)

m<DCF = 133°

Opposite angles in an inscribed quadrilateral are supplementary.

Therefore,

m<DEF = 180° - m<DCF

m<DEF = 180° - 133°

m<DEF = 47°

Answer: A=(5,2) B=(5,-1) C=(6,-1) D=(6,2)

Step-by-step explanation: part D: The x-coordinates of the translated figure are 2 more than the original x-coordinates. The y-coordinates of the translated figure are 4 less than the original y-coordinates.

Part E: A translation of two yards east involves moving 2 units in the positive x-direction. Given any initial x-coordinate, x, the algebraic expression that represents the new x-coordinate after the translation is x + 2.

Part F: A translation of four yards south involves moving 4 units in the negative y-direction. Given any initial y-coordinate, y, the algebraic expression that represents the y-coordinate after translation is y + (-4).

Part G: Combining the expressions from parts E and F, for any given initial point (x, y), the coordinates of the new point after a translation of two yards east and four yards south are (x + 2, y + (-4)).

can you help me with one of my question

Step-by-step explanation:

what do you mean lf speed is not given what we have tofind

Answer:

v = d/t, perhaps.

Step-by-step explanation:

Velocity (speed) is defined as distance traveled divided by the time it takes to travel that distance.

This gives an average speed.  For example, I'll be taking a trip tomorrow of about 150 miles.  If it takes me 3 hours, my average speed is v = 150/3 = 50 miles per hour.

That does not mean my speed is constantly 50 miles per hour; I sometimes go slower than that (maybe even stopping for red lights!), and sometimes I'll be going faster than that.

A lot of school math problems assume a constant speed.

do problem like image attached

[tex] - 4a - (8a + 1) = - 169 \\ \\ 4a + 8a + 1 = 169 \\ \\ 4a + 8a = 169 - 1 \\ \\ 12a = 169 - 1 \\ \\ 12a = 168 \\ \\ a = \frac{168}{12} \\ \\ a = 14 \\ \\ this \: was \: helping \: you[/tex]

Step-by-step explanation:

Okay so remember the BODMAS rule where u start with brackets right; Since we're proving that RHS =LHS ,we look at the side which is more complicated and solve it first.

RHS: -4a-(8a+1) =-169

-4a-8a-1=-169

-4a-8a= -169+1 ( N:B like terms)

-12a= -168

-12a/-12= -168/-12

a= 14

Then go back to the original equation and subtitute .

where u see a u put the value u calculated.

-4a-(8a+1)=-169

-4(14)-(8(14)+1)= -169

-169= -169 and u DONE!!

Using the model to predict, the number of pieces  in the Star Wars LEGO Death Star™ set is:

MODEL TO PREDICT.

To predict the cost of a thing or its number with previous data, in this case pieces of a set, you can follow the next steps:

1. Make a graph with that has the price in the y-axis, and the number of pieces in the x-axis (Picture 1).

2. Add all the data you can use for this exercise, for example, the small LEGO set that bought Mackenzie in $5.49 with 43 pieces (Picture 2).

3. You must draw the trend line to define the formula of the model (Picture 3).

4. The formula of the model is y = kx, where k is the value of the trend line (0.12 approximately given by the graph), with this the formula would be y = 0.12x.

5. As you know, the y variable is the price and the x variable is the number of pieces, how you have the price given in the exercise ($499.99), you can solve x, replace y value and calculate the number of pieces:

y = 0.12x

x = y / 0.12

x = 499.99 / 0.12

x = 4166.58

x ≅ 4167 pieces.

As you can see, the number of pieces calculated with the formula from the model is 4167 pieces.
